Control Test of Three New Fungicides on Peanuts Rust

[目的]筛选防治花生锈病的新型杀菌剂。[方法]采用喷雾法喷施不同浓度的新型杀菌剂,调查花生叶片药前及药后的病情指数和防治效果。[结果]70%甲基疏菌灵对花生锈病具有较好的防治效果,2次药后7天在120 g a.i./hm2剂量下的防效可高达88.1%,而80%进口多菌灵和40%氟硅唑多菌灵的防治效果一般。[结论]70%甲基疏菌灵在120 g a.i./hm2剂量下对花生的锈病防治最好。

[Objective] Screening the new fungicide of peanuts rust prevention.[Method] By spraying different concentrations of new fungicide, disease index and control effect of peanut leaf was investigated before and after the drug treatment. [Result] 70% methyl hydrophobic bacterium spirit to peanuts rust had good control effects 88.1% of seven days after the two times drug with 120 g of a.i. / hm2 doses control. The control effect of 80% and 80% carbendazim and fluorine silicon were common. [Conclusion] The control effect of 70% methyl hydrophobic bacterium spirit of 120 g of a.i. / hm2 doses prevention was the best.
